Cagayan's at-large congressional district may refer to three occasions when a provincewide at-large district was used for elections to the various Philippine national legislatures representing Cagayan.

From 1898 to 1901, three representatives (two appointed and one elected) sat in the Malolos Congress, the national assembly of the First Philippine Republic. Cagayan was reorganized under the Philippine Insular Government in 1901 and was divided into two districts for the Philippine Assembly in 1907. From 1943 to 1944, the province as a whole sent two representatives to the national assembly during the Second Republic. Multiple-district representation was restored in the province in 1945.

In 1978, regional at-large assembly districts were created for the Interim Batasang Pambansa, the national parliament, with Cagayan included in the 8-seat Region II at-large district. The province returned to its own single, multi-member at-large district in 1984, with a three-seat delegation to the Regular Batasang Pambansa during the Fourth Republic. After 1986, Cagayan elected its representatives from its separate congressional districts. The district was last represented by Antonio Carag, Juan Ponce Enrile, and Alfonso Reyno Jr. of Kilusang Bagong Lipunan (KBL).
